European-Type Prefabricated Substation
Equipped with comprehensive protection functions, the system is fully scalable with no capacity limitations.
Product Description
YB-12/24/40.5 prefabricated substation (intelligent integrated substation) pre-assembles components such as high-voltage switchgear, power transformers, low-voltage switchgear, energy metering equipment, reactive power compensation devices, auxiliary equipment, and connecting parts within a single enclosure. It is suitable for locations with small and dispersed loads, including public building complexes, residential quarters, scenic areas, tourist spots, and urban roads.
Product Advantages
Low Loss, Worry-Free Durability
Utilizing a low-loss, low-temperature-rise, and low-noise transformer, the system features a fully sealed, maintenance-free design that easily satisfies short-term full-load and overload requirements.
Compact Footprint, Worry-Free Installation
Featuring a high-strength frame, the internal layout is configured in an F-type or T-type arrangement, divided into a high-voltage room, transformer room, and low-voltage room. It features a compact footprint and adapts perfectly to multiple scenarios.
Modular Design, Worry-Free Upgrades
Both high-voltage and low-voltage units feature independent modular designs, making it easy to add motorized operating mechanisms and data acquisition units for highly flexible expansion.
Efficient Cooling, Worry-Free Stability
Each compartment features natural ventilation and built-in indoor lighting. The transformer room is equipped with temperature-controlled exhaust fans to ensure long-term equipment stability.
